MONCBSTRUCT

The MONCBSTRUCT structure contains information about the current DDE transaction. A DDE debugging application can use this structure when monitoring transactions that the system passes to the DDE callback functions of other applications.

typedef struct tagMONCBSTRUCT { 
  UINT   cb; 
  DWORD  dwTime; 
  HANDLE hTask; 
  DWORD  dwRet; 
  UINT   wType; 
  UINT   wFmt; 
  HCONV  hConv; 
  HSZ    hsz1; 
  HSZ    hsz2; 
  HDDEDATA hData; 
  ULONG_PTR dwData1; 
  ULONG_PTR dwData2; 
  CONVCONTEXT cc; 
  DWORD  cbData; 
  DWORD  Data[8]; 
} MONCBSTRUCT, *PMONCBSTRUCT;

Members

cb: Specifies the structure's size, in bytes.
dwTime: Specifies the Windows time at which the transaction occurred. Windows time is the number of milliseconds that have elapsed since the system was booted.
hTask: Handle to the task (application instance) containing the DDE callback function that received the transaction.
dwRet: Specifies the value returned by the DDE callback function that processed the transaction.
wType: Specifies the transaction type.
wFmt: Specifies the format of the data exchanged (if any) during the transaction.
hConv: Handle to the conversation in which the transaction took place.
hsz1: Handle to a string.
hsz2: Handle to a string.
hData: Handle to the data exchanged (if any) during the transaction.
dwData1: Specifies additional data.
dwData2: Specifies additional data.
cc: Specifies a CONVCONTEXT structure containing language information used to share data in different languages.
cbData: Specifies the amount, in bytes, of data being passed with the transaction. This value can be more than 32 bytes.
Data: Contains the first 32 bytes of data being passed with the transaction
(8 * sizeof(DWORD)).

Requirements

  Windows NT/2000: Requires Windows NT 3.1 or later.
